yo have to weld it correctly and weld all the spiders together.

if the welds break, good game.

You don’t need to weld the spiders completely.

As long as you get good penetration, it won’t matter.

Too much weld = too much parasitic loss.

There’s a great trick to it.

Avery, I’ve got a spare R200 short snout (not out of a 240, but same diff) I’d donate to the cause. I just have to pull it and swap my LSD in - and, well I’m lazy and the car still moves 😉

I have one you can weld, but I don’t want to donate it.

Lemme know if that works for you…

one question, how strong of a welder do you need to weld up your diff properly?
